Get Priceaggregate crushing value provides a relative measure of the resistance of an aggregate to crushing. The standard test is made on dry aggregate passing a 13.2 mm AS sieve and retained on a 9.50 mm AS sieve and is performed in duplicate. This method conforms to the method described in Australian

Get PriceCalculation of aggregate crushing value. The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here 2.36mm sieve) to the total weight of sample expressed in percentage. W1= Weigh of the total aggregates (Wa-We) W2= Weigh of aggregates passing through 2.36mm IS sieve.

Get PriceAggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate used in road construction is expressed by numerical index.

Get PriceThe aggregate crushing value (ACV) provides relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Two versions available: 150 (standard) and 75 mm dia. The apparatus comprehend cylinder, plunger, base plate, tamping rod and measure.

[PDF]Get PriceThe laboratory CWi value of 27.4 (metric) is almost within 4.5 units of the 22.4 value I calculated, so what you are observing is probably the natural variation in the crushing test. So there is nothing wrong with your calculation, and the variation between the laboratory test and your observation of the operating crusher is within the normal range of variation for this calculation.
